摘要： A method for detecting CH.sub.4 with a Ga.sub.2 O.sub.3 sensor, and a method for measuring CH.sub.4 concentration with a Ga.sub.2 O.sub.3 sensor is provided. In order to solve the problem associated with the masking or disturbing effect alcohol has on the detection of methane with a gallium oxide detector, the present invention provides a method where the sensor conductivity ((G(t.sub.1)) is acquired at a first sensor temperature, and is compared with a first threshold value. If the conductivity ((G(t.sub.1)) exceeds this threshold value, it is determined that alcohol is present in the gas mixture to be examined. The sensor is then heated, and a second conductivity (G(t.sub.2)) is acquired. If the ratio of the second to the first conductivity exceeds a second threshold value, CH.sub.4 is likewise present in the gas mixture. The measurement of the CH.sub.4 concentration ensues by means of an acquisition of two conductivities (G(t.sub.1), G(t.sub.2)) at different temperatures. The corresponding CH.sub.4 value can be taken from a table or reference plot.

摘要： The method reduces the nitrogen oxide concentration in the exhaust of an internal combustion engine. A noticeable reduction in the NO.sub.x emission of a diesel motor can be achieved by applying the Selective Catalytic Reduction (SCR) method. In this method, ammonia is injected into a catalyzer through which the exhaust gas flows, this ammonia reacting with nitrogen monoxide or, respectively, nitrogen dioxide to form nitrogen and water. Since the exhaust gas should contain neither nitrogen monoxide nor excess ammonia, suitable methods are required for regulating the metering of NH.sub.3. For controlling the amount of urea added to the exhaust gas as a reduction agent, the NO and NH.sub.3 concentration is measured using a detector located in the exhaust systems following the SCR catalyzer. The detector contains a vanadate layer manufactured on the basis of a specific sputtering method as a sensitive element. The electrical resistance thereof is highest when the conversion of nitrogen monoxide to form nitrogen and water occurs stoichiometrically.

摘要： A method and apparatus for detecting methane in a gas mixture that may contain commonly used solvents including alcohols and acetones is provided which measures a change in electrical resistivity, electrical conductivity or relative permeability caused by the presence of methane gas at a chemically active sensing structure. The apparatus includes two spaced-apart electrodes that are covered with a thin methane-sensitive semi-conductive metal oxide layer. The gas to be tested is heated to a temperature exceeding 740.degree. C. before it contacts the metal oxide layer. Alcohols, acetones and other solvents are oxidized to electrical carbon dioxide and water before they reach the metal oxide layer so that only the less reactive and reducing gas methane reaches the metal oxide layer where it is reduced and increases the conductivity of the metal oxide layer as measured between the two spaced-apart electrodes with an appropriate electrical meter instrument.
